I Specification of Letters Patent.

Patented May 13, 1913.

Application filed April 6, 1912. Serial No. 688,918.

To all whom it may concern Be it known that I, JAMES F. HIGKEN- BOTTOM,a citizen of the United States, residing at Flora, in the county ofClay, State of Illinois, have. invented certain new and usefulImprovements in Dampers for Heating-Stoves; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to dampers for heating stoves.

The object of the invention resides in the provision of a damper forheating stoves which will be simple in construction, eflicient in useand which may be manufactured and installed at a comparatively smallcost.

With the above and other objects in view, theinvention consists in thedetails of construction and in the arrangement and combination of partsto be hereinafter more fully described and particularly pointed out inthe appended claim.

In describing the invention in detail, reference will be had to theaccompanying drawings, wherein like characters of reference denotecorresponding parts in the several views, and in which Figure 1 is ahorizontal section of a heating stove having the improved damperassociated therewith. Fig. 2 an inside view of the feed door of thestove detached. Fig-3 an outside view of the feed door detached, andFig. 41 a section on the. line tt of Fig. 3.

Referring to the drawings, the stove is shown as comprising outer andinner casings 10 and 11 respectively, the former of which has an openbottom while the latter has the greater portion of its side walldisposed in spaced relation to the side wall of the outer casing. Theside wall of said inner casing is disposed in engagement with the sidewall of the outer casing at the front side of the latter and saidengaging port-ions of the side walls of said casings are provided withregistering openings adapted to be closed by a door 13 hinged to theouter casing 10. The inner casing is secured within the outer casing bymeans of bolts 14:.

The door 13 has formed integral thereagainst the inner face of theflange 22 is a plate 23 having diametrically oppositely disposedinwardly directed ears 24 suitably secured to the tubular portion 21 tohold the plate in position against the inner face of the flange 22. Thisplate 23 is provided with spaced openings 25 and also inwardly directedears 27 disposed at the adjacent edges of said opening and bent so as toretain therebetween a member 28 having a threaded opening 29 extendinglongitudinally therethrough which registers with an opening 30 formed inthe plate 23. Mounted in the openings 30 and 29 is the threaded end of abolt 31. This bolt carries intermediately a disk 32 secured in place bya looking nut 33 mounted on the threaded end of the bolt 31. By thisconstruct-ion it will be apparent that the bolt 31 may be manipulatedtoward and away from the plate 23 so as to close or uncover the openings25 and thus control the draft of the stove.

What is claimed is:

In a heating stove the combination of a body having an opening therein,a door hinged to the body for closing said opening, said door beingprovided with an opening in its lower end, an outwardly extendingtubular port-ion, an inwardly directed flange on the outer end of saidportion, a plate disposed against the inner face of said flange andsecured to the tubular portion, said plate being provided with spacedopenings, inwardly bent cars at the adjacent edges of said openings, ablock clamped between said ears provided with a threaded passage andregistering with an opening in said plate, a bolt mounted in saidthreaded passage, a disk carried by said bolt and disposed outwardly ofsaid plate whereby the rotation of the bolt will move the disk to coverand uncover the openings in the plate, and said outer casing beingprovided with perforations in its top portion.

In testimony whereof, I afiix my signature, in presence of twowitnesses.

JAMES F. HICKENBOTTOM.
